The Grundfos MAGNA3 pumps are a range of small, medium and large circulator pumps fitted with electronically controlled motors based on permanent magnet (PM) and compact stator technology.
With the MAGNA3, you can stop worrying about which pump setting to choose. Simply install the pump and leave it on the factory AUTOADAPT setting. The unit will then analyse the heating system demands and find the optimal setting. It will then continuously adjust its operation to changes within the system demand. The result is optimal comfort and minimum energy consumption.
MAGNA3 pumps are extremely flexible and reliable, and have low noise levels, long life and minimum maintenance requirements. They are fitted with GENIair wireless communication as standard and can also be expanded to offer extended control options with Communication Interface Modules (CIM).
